Blinding of testosterone therapy trials is particularly difficult. Increased hirsutism can be easily hidden by plucking. For many women, facial hair growth is a very private concern and disclosure is difficult. A further complexity is the possibility that the improved mood potentially even mania [ Weiss et al. Robust association between low desire and depression has been repeatedly demonstrated [ Lutfey et al.
Recent empirical research confirms that an experimentally induced happy or sad mood can impact subjective sexual arousal but not objective vaginal congestion as measured by a vaginal photoplethysmograph , with subjects reporting significantly less subjective arousal and marginally significant fewer genital sensations when a negative mood was induced prior to viewing an erotic film clip [ ter Kuile et al.
Whether the benefit continues well beyond 6 or 12 months is unclear. Long-term safety issues include those of the combination of testosterone and estrogen as well as current concerns about estrogen itself. The former are not known beyond 3 years. While most of the patch studies were of 6 months duration, women in two of the studies could enroll into open-label extensions.
Only an abstract is available [ Nachtigall et al. No clinically relevant changes in liver function, carbohydrate metabolism, lipids, clotting parameters or hematology were noted. No placebo group was followed simultaneously. Three cases of invasive breast cancer occurred, which was considered to be consistent with age-expected rates.
There has been criticism that the target high normal serum concentrations of testosterone and dihydrotestosterone were exceeded in a significant number of women in the patch studies [ Arlt, ]. Indirect data support both risk increase and decrease for breast cancer from testosterone supplementation: a recent review concludes that the available clinical literature does not permit conclusions on safety [ Bitzer et al.
In contrast to the situation in men, women with high endogenous testosterone are more likely to develop insulin resistance and cardiovascular risk [ Brand and van der Schouw, ; Wild, ], but how this relates to postmenopausal testosterone therapy is unknown.
Currently long-term estrogen therapy is not advocated. Women beginning estrogen therapy at menopause may show cardiovascular benefit rather than harm, but there is no evidence that after 10—15 years of exogenous estrogen supplementation endothelial function is preserved in a healthy state such that estrogen can be prescribed indefinitely to these women.
Women's sexual lives however, tend to continue as long as they have a sexually active partner. Thus, the long-term safety of estrogen and testosterone received systemically is currently unknown but is crucial. For many of these reasons the American Endocrine Society currently advises against testosterone supplementation for women [ Wierman et al.
Lack of attraction to the partner, negative feelings for the partner at the time of sexual interactions [ Bancroft et al. DSM definitions of women's sexual disorders are being revised currently [ Brotto, ; Graham, ]. A detailed review of the data supporting the concept of a SIAD has been recently published [ Brotto, ]. Specifically there needs to be an absence or paucity of desire initially and an absence or paucity of desire triggered during the sexual experience for this disorder to be diagnosed.
As well as including women with more definite dysfunction SIAD rather than HSDD , trials must extend well beyond the typical 2—3 years of safety monitoring for all the reasons mentioned previously. Given the wide range variables in the amount of hormone or precursor hormone produced in the activity of enzymes converting precursor hormones to active sex hormones, the sensitivity of the androgen and estrogen receptors, and the relative importance of neurosteroids versus systemic sex steroid production, individualized therapy taking these factors into account would be a future ideological goal.
Considering that testosterone and estrogen inherently possess many nonsexual actions, supplemental therapy may have a too high potential risk of adverse effects.
This may lead to molecules conferring greater sexual benefit-to-risk ratios and added benefits on breast health, cardiovascular health, and glucose metabolism as well as the health of the endometrium and bone density. Some two million prescriptions for off-label compounded formulations of testosterone were written for women in — by American physicians [ Snabes and Simes, ]. The uncertainty of long-term safety, particularly cardiac, precluded approval of transdermal testosterone by the FDA in , but did little to reduce off-label prescribing.
The situation is clearly of concern, particularly as no scientific monitoring of this extensive off-label prescription is likely to occur. Although clinicians sometimes prescribe topical testosterone to be used sparingly on the vulva in an attempt to restore lost sexual sensitivity of tissues comprising and overlying the clitoris, this practice has not been scientifically studied. Recently however, local delivery of the main precursor hormone, namely DHEA, into the vagina was reported to not only efficiently reverse estrogen deficiency-associated vulval vaginal atrophy, but to restore genital sexual sensitivity, such that orgasms were more easily obtained and more intense [ Labrie et al.
Moreover, the desire item on the questionnaire used in the study also improved significantly compared with placebo. This therapy appeared to be truly local as there was no increase in serum DHEA, estrogen or testosterone. Further study is needed to confirm these results. We do not have evidence of low androgen activity in women with low sexual libido.
We do know that scope of measurement is limited. Although we are now able to quantify intracrine testosterone, we cannot measure testosterone production and activity within the central nervous system, which maybe more relevant to sexual desire.
We also have no information on androgen receptor sensitivity in women with and without sexual dysfunction. We do not have studies of testosterone supplementation in women with definite sexual disorders, where criteria for diagnosis of disorder are more robust. We do have evidence of modest increase in numbers of sexually rewarding events in women who without any treatment are able to have 2—3 such events per month.
In North America, testosterone therapy is not approved for women. There are transdermal formulations specifically approved for men, testosterone gels and patches. Dosage is flexible with the former but not the latter the patches should not be cut. However, there is uncertainty over the amounts absorbed and lack of scientific study of this practice is worrisome.

Even with testosterone gels and patches that have been approved to treat men, there is still a lack of data on how much testosterone actually gets absorbed. That, combined with its known side effects, makes testosterone supplementation more concerning. Long-term testosterone supplementation increases a man's risk of cardiovascular problems like stroke, heart attack, and fatal heart disease.
Some medical professionals are also concerned that testosterone supplementation could stimulate the growth of prostate cancer cells. In place of the patch, there are two drugs approved for the treatment of HSDD in women. The first is Addyi flibanserin , a non-hormonal pink tablet indicated for use by premenopausal women.
The other is Vyleesi bremelanotide , an injectable drug used to treat acquired HSDD in women who haven't reached menopause yet. Although unapproved, Viagra has also been investigated for use in treating female sexual dysfunction and it is sometimes prescribed off-label.
If female sexual dysfunction FDS is caused by or related to an underlying medical condition, the management and treatment of the condition should be examined and optimized. For instance, medical conditions like diabetes and multiple sclerosis have been known to contribute to female sexual dysfunction.
Further, some of the medications used to treat conditions like hypertension have side effects that negatively impact arousal.
If after investigation, your healthcare provider finds that a particular medication is the cause of your FSD, the dosage of the offending drug can be adjusted.
Finally, to treat sexual dysfunction caused by antidepressants SSRIs in particular , central nervous system medications may be prescribed. Studies have shown that high doses of bupropion mg twice daily have shown promise in treating SSRI-related sexual dysfunction in women.
While you can get access to testosterone through off-label prescriptions and online supplements , given the absence of solid supporting evidence, it's probably best that you steer clear of it.
Testosterone is a hormone, and hormones have been known to have potential adverse effects like stroke, blood clots, cancer and so forth. Pursuing other treatment options, like seeing a therapist, maybe more beneficial for you in the long run.
